Too big energy usage for one device, how to trace reason

Hi,
I just spotted that from like February my microwave energy usage is growing 10 times more it should. I have like 10+ devices connected through different Sonoff POW’s, microwave is one of them. All other readings in HA are correct except that one. On Sonoff POW side (ewelink app) the readings are CORRECT. How to trace where the fake energy used is coming from?

Microwave powered on for 1 minute today:



It uses like 1.2-1.3kW, so for 1 minute 0,02kWh is correct.

Now let’s zoom out for last 2 days:

We have 3 short runs similar to the one above but overall energy consumed increased from 229,53 to 230,08 which gives 0,55 instead of 0,06. Almost 10 times more.


I checked config like 15 times, searched by device IDs they are unique, no other device is linked to the same energy usage entity.

configuration.yaml:

- platform: integration
  name: energy_spent_mikrofalowka
  source: sensor.sonoff_10007c8723_power
  unit_prefix: k
  round: 2

customize.yaml

sensor.energy_spent_mikrofalowka:
  device_class: energy
  unit_of_measurement: kWh
  friendly_name: Mikrofalówka

It was working for like 2 or more years, nothing was changed in configuration.

- platform: integration
  name: energy_spent_mikrofalowka
  source: sensor.sonoff_10007c8723_power
  unit_prefix: k
  round: 2
  method: left  ##### <-----------add this

Wow, seems it works like a charm. Thank You!
